STEAM-WATER HEATER AND PURIFIER.

SPECIFICATION forming part of Letters Patent No. 439,574, dated October 28, 1890. I Application filed June 277, 1890. Serial No. 356,963- (No model.)

To all whom it may concern.-

Be it known that I, JOHN BRYCE, a citizen of the United States, residing at Moberly, in the county of Randolph and State of Missouri, have invented a new and useful Steam-Water Heater and Purifier, of which the-following is a specification.

My invention relates to improvements in steam-water heaters and purifiers that are specially adapted to railroad-locomotives; and the objects of my improvement are, first, to precipitate any impurities of the water before it enters the main boiler; second,afford greater facilities for heating the water before it enters the same, and, third, to provide means for readily cleansing the boiler and supply apparatus connected therewith from sediment without impairing power and prevent scalin g. I attain these objects by the mechanism illustrated in the accompanying drawings, in which- Figure I is a top view of a locomotive-boiler provided with my improvement. Fig. II is a side elevation of a boiler, showing one side, with the lower drum and connections of my apparatus. Fig. III is a cross-sectional view on line 3 3, Fig. II, of a boiler provided with my improvement. Fig. IV is a longitudinal view in cross-section on line 4 4, Fig. III, of the right-side drum; and Fig. V is a similar view of the left-side drum on line 5 5, Fig. III, showing the fines and circulation of the water in the drum and pipes coursing in the direction of the feathered arrows.

Similar letters and figures refer to similar parts throughout the several views.

The locomotive-boiler A, its fire-box a, smoke-arch a, dome a together with the longitudinal heating and circulating drums O O, and lower drum B, constitute the body or frame-work of the machine. The side drums C and C are made of sheet-steel rolled in circular form and riveted. They are each about fifteen feet in length and one foot in diameter, and are provided inside with one or more fines (the drawings show three) for conveying heat from the fire-box a to the smoke-arch a. Below the fines and inside the drum 0 are also placed the receiving-pipes e, (about two and one-half inches,) which lead from the injectors E E, respectively. Each pipe traverses nearly the length of the drum and is attached in pairs by a U-pipe connection 6' for returning the water to the point of discharge into the drum 0 at 6 Fig. V. ,The drums O O are connected with the fire-box a by means of the funnel-shaped piece 6 made of the same material as the drums and attached thereto by a metal ring or flange 0 from whence they taper to fit about a six-inch opening in the fire-box'at c','which receives them. The outer ends of the drums G C are connected by a similar piece 0, that tapers from the connecting-flanges c to a three and threeqnarter inch opening 0 in the smoke-arch, the ends of the pieces 0 turning upwardly before they discharge in the smoke-arch in the manner indicated by dotted lines, Figs. I and II. The injectors E E are placed near each other on one side of the cab, and are connected with the pipes e e of the drum 0 by a check-valve at the point e in conjunction with the leaders e and elbows 6 The water from the injectors entering the drum 0 from below in the manner shown traverses the length of the pipes e 6 (receiving heat from the fines c c) and being discharged therefrom into the drum 0, from whence it passes through the opening of the pipe F, which conveys it underneath the main boiler to the drum 0 in the manner shown in dotted lines, Fig. I, and by the pipe F, Fig. III, the pipe F being extended inside the drum 0' from front to rear end, where it is discharged into the body of the latter at the opening f the water passing thence, after being again subjected to the heated fines, from the drum G to the lower drum B by a four-inch deflected pipe G, which leads from the drum G at the point shown in dotted lines at g, Fig. II, to the lower drum B, and entering the latter from below at its forward end it traverses the U-shaped pipe I) 1) (shown in dotted lines) to where the lat ter discharges the same into the body of the lower drum B at the opening I). The drum B is about twelve feet in length by about twenty-three inches in diameter, and is of sheet-steel rolled in circular form and riveted like the drums O C and headed. From the drum B through the groin-joint and globevalve connection b b and b the heated and purified water first enters the main boiler A by its bottom part in the manner shown in Fig. II. I also connect the steam-dome a with the drums C and C by an opening in the former at N, Fig. II, in which I insert a two-inch pipe leading downward and connecting with the drums C and O on both sides at the points 12 The dry steam from the dome is thus led to the Water in the side drums O and C, and eommingling therewith aids in heating and purifying the supply.

At the rear end of the lower drum B, near the bottom, is placed a two and a half inch plug-valve II for the purpose of blowing off the sediment and refuse matter in the pipes, drums, and boiler. This is done by opening the valve H and letting on the injectors, the globe-valve Z1 being first closed, so as to cut off communication between the boiler and drums, and acting on the latter first and then opening the globe-valves the entire boiler and drums and pipes are all blown out and cleansed. It may thus be readily seen that the boiler and apparatus may be kept clear and the auxiliary drums and pipes cleansed while the steam-power remains intact.

Having thus described my invention, What I claim as new, and desire to secure by Letters Patent, is-

1. The combination, with the boiler, of the drums C C, arranged on the sides thereof, the drum B below the boiler, provided with the valve H at one end, the valve b controlling the communication between the drum B and the boiler, a pipe connecting the drums C C, a pipe connecting the drum 0 with the drum B, and the injectors at the rear end of the drum 0, communicating therewith, as set forth.

2. The combination, with the boiler having the firebox a and the smoke-arch a, of the drums C 0', arranged on the sides of the boiler, the tapered caps c 0, connecting the ends of the drums with the fire-box and smokearch, respectively, pipe F, connecting said drums, the drum B below the boiler and connected therewith, pipe G,connecting the drums O B, and suitable means for admitting water to the drum 0, as set forth.

3. The combination, with the steam-boiler, of a drum on the side of the same, having its ends communicating with the fire-box and smoke-arch of the boiler, water-connections between the drum and the boiler, and the inj ectors or feed-water supply at one end of the drum, as set forth.

4. The combination, with the boiler, of the drums G C on the sides thereof, having their ends communicating therewith and provided with heating-fines c, the injectors E at the rear end of the drum C, the return-pipes e in the drum G, connected with the injectors, the pipe F, extending from the drum C below the boiler to the drum C and then longitudinally within the said drum to near the rear end of the same, the drum B below the boiler, the

pipe G, connecting the drums C B, the returnpipe 1) within the drum B, and a valved c011- neetion between the drum B and the boiler, as specified.
